Did you know you could make electricitypower with a potato? The chemical reactions that take place between two dissimilar metals and the juices in the potato create a small amount of voltage that can power a very small electrical device. There are potato-powered clocks, small computers, and even one small sound system powered by 500 pounds of taters.
But how many potatoes does it take to power your house? Movoto created a calculator that will tell you how many you'd need to power your entire home.
